Abstract
A flame-retardant polycarbonate resin composition comprising either a resin mixture of a polycarbonate resin and a styrenic resin, a functional group-having silicone compound, and a fluoro-olefin resin; or a polycarbonate resin, a functional group-having silicone compound, and a core/shell-type, grafted rubbery elastomer; or a resin mixture of a polycarbonate resin and a styrenic resin, a fluoro-olefin resin, an inorganic filler, and a polycarbonate-polyorganosiloxane copolymer and/or a functional group-having silicone resin, which composition and its moldings, exhibit good flame retardance, good impact resistance, and good thermal stability.
Claims11
A flame-retardant polycarbonate resin composition comprising 100 parts by weight of a resin mixture of (A) from 50 to 90% by weight of a polycarbonate resin and (B) from 10 to 50% by weight of a ABS resin, from 0.01 to 5 parts by weight of (D) a fluoro-olefin resin, from 2 to 70 parts by weight of (F) talc, and from 1 to 500 parts by weight of (G) a polycarbonate-polyorganosiloxane copolymer, wherein the polydimethylsiloxane content of the polycarbonate-polyorganosiloxane copolymer (G) is between 1 and 10% by weight and wherein the viscosity-average molecular weight of (G) is between 10,000 and 30,000 and wherein the silicone content derived from the component (G) falls between 0.3 and 10% by weight of the composition.
